Galactic Purple GloFish Danio
The Asians created GloFish® by splicing the genes of zebra danios and hi-fin white skirt tetras with phosphorescent corals and jellyfish. The fish were patented and licensed for sale in the USA several years ago once the FDA determined them to be safe for the environment. Though these fish do not actually glow in the dark, they are truly fluorescent and will keep that bright color throughout their lifespan.

I bought this fish for my first aquarium. It’s colorful and peaceful. The fish don’t seem to fade over time, which is a plus. I would recommend it to anyone starting with fish.

The fish arrived quickly and looked healthy. They’ve been in the tank for two months and still show strong purple fluorescence. Very satisfied with the purchase.
